What should I do if I am not getting any sound from the center or the right speaker?

Center Speaker
Check the speaker wire connection on the back of the unit. Unplug the speaker wire from the back of the unit, and then reinsert it into the center speaker slot on the back of the unit. Next, go to the unit's audio settings and perform a speaker test. If you are using a stereo channel source or the unit has no center channel encoded, turn on the "Super Surround" option.

Right Speaker
The right speaker of the center channel is a "Super Tweeter" it along with the full range speaker produce a more natural sound even though you may not hear audio coming from the super tweeter. Super tweeters produce high frequencies which may not be heard at all times.
